10 Performing GO/NO-GO Determination Using
Measured Values of Power Analysis Parameters
Procedure
• To exit the menu during operation, press ESC located
above the soft keys.
• In the procedural explanation below, the term
jog shuttle & SELECT refers to the operation of
selecting/setting items and entering values using the jog
shuttle , SELECT and RESET keys. For details on the
operation using the jog shuttle, SELECT, and RESET, see
sections 4.1 or 4.2 in the
DL7440/DL7480 User’s Manual .
• For a description of the operation using a USB keyboard or
a USB mouse, see section 4.3 in the DL7440/DL7480
User’s Manual .

To perform GO/NO-GO determination using power analysis parameters, you must
turn ON the power analysis function on the applicable channels. For the setup
procedure, see section 3 in this manual.
Note
To make correct measurements and computation, it is recommended that the difference in
the transfer time of the analyzed signals be corrected (deskewed). For the setup procedure,
see section 4 in this manual.
1. Press GO/NOGO . The GO/NO-GO menu appears.
The rest of the procedure is the same as steps 2 to 13 in section 10.10 (pages 10-72 to
10-74) in the DL7440/DL7480 User’s Manual IM701450-01E .
If power analysis is enabled on the target waveform, power analysis parameters can be
selected as measurement parameters.
Explanation
As with the standard measurement parameters (waveform parameters), you can perform
GO/NO-GO determination using power analysis parameters. GO/NO-GO determination
can be performed on whether the measured value of the measurement parameter leaves
or enters the range specified by upper and lower limits.
The measurement parameters vary depending on the target waveform used in the
determination. The measurement parameters are the same as the “Search
Measurement Parameters” in section 9 (page 31) in this manual.
For a detailed explanation on GO/NO-GO determination using measured values, see the
explanation given in section 10.10 (pages 10-74 and 10-75) in the DL7440/DL7480
User’s Manual .
Note
• You cannot perform history search on computed waveforms Math1 or Math2 that are set to
waveform computation of harmonics or whose trend is displayed.
• You cannot perform GO/NO-GO determination on the measured values of waveform
parameters or zones for computed waveforms Math1 or Math2 whose trend is displayed.
